If you're seeing a blue tinge, it means that the blue component cables are either loose or they may have a small break within them. I would unplug the blue component cables from your set top box and the Slingbox and then plug them back in, making sure they are snug. This should fix the issue, but please let me know if it does not!
New User. Slingbox 500 connected to Cox contour 4742hdc; blue color on most items on screen. iPhone watching contains lot of jitter. Speed tests all good. Tells me to connect HDMI cables, but HDMI cables ARE connected with 500 between Contour and TV. Thoughts?
